Rose plant named Mac Compu

ABSTRACT

A new and unusual bright orange and yellow bicolor Grandiflora rose.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of roseplant of the Grandiflora rose class, which was originated by my crossingas seed parent and as pollen parent two unnamed, unpatented seedlings ofmy creation. The varietal denomination of this new rose is "Mac Compu".

Among the novel characteristics possessed by this new variety whichdistinguish it from its parents and all other varieties of which I amaware are its unusual bright orange and yellow bicolored flowers in thisclass of rose. Flowers are long lasting on the plant and after cutting.Asexual reproduction by budding of the new variety as performed in SmithCounty, Tex., shows that the foregoing and other distinguishingcharacteristics come true to form and are established and transmittedthrough succeeding propagations.

BRIEF DESCRIPTION OF DRAWING

The accompanying drawing shows typical specimens of the vegetativegrowth and flowers of the new variety in different stages of developmentdepicted in color as nearly true as it is reasonably possible to makethe same in a color illustration of this character.

DESCRIPTION OF PREFERRED EMBODIMENT

The following is a detailed description of my new variety, with colorterminology in accordance with The Royal Horticultural Society ColourChart (R.H.S.C.C.). The terminology used in color description hereinrefers to plate numbers in the aforementioned color chart, e.g., "28A"is plate 28A of The Royal Horticultural Society Colour Chart.

Parentage: Seedling.

Seed parent.--Unnamed seedling.

(5) Color.--After sepals fall and petals unfurl, predominant flowercolor viewing petals' top surface is near 28A to 21D with flowersvarying in color through this range producing an overall bright orangecolor effect. Flowers exhibit deeper toned orange suffusion morepronounced in outer petals which are deeper toned than inner petals.Petal undersurface tends toward near 13B suffused with near 28B. Colorat point of petal attachment is near 15C. Overall tonality from adistance is bright orange, near 25A to 28A. Color changes as blooms ageto near 25A to 28B.

(4) Arrangement.--Regularly arranged, imbricated.

(5) Petaloids in center.--Few.

(6) Persistence.--Average.

(7) Fragrance.--Slight.

(8) Lasting quality.--Average.

REPRODUCTIVE ORGANS

A. Stamens, filaments and anthers:

(1) Arrangement.--Regularly arranged around styles.

(2) Color.--Filaments yellow.

B. Pollen:

Color.--Yellow.

C. Styles: Even, medium length.

D. Stigmas:

Color.--Ivory.

E. Hips: Globular, average size, orange red color, seeds sometimesprotrude.

PLANT

A. Form: Spreading.

B. Growth: Average vigor.

Height attained.--About 31/2 feet to 4 feet.

C. Foliage: Compound 5 leaflets.

(1) Size.--Medium.

(2) Quantity.--Abundant.

(3) Color.--New foliage: Upper side -- near 144A. Under side -- near182B. Old foliage: Upper side -- near 141B. Under side -- near to 138B.

(4) Shape.--Oval, pointed.

(5) Texture.--Upper side is glossy and under side is matte.

(10) Resistance to disease.--Blackspot -- Average. Mildew -- Good.

D. Wood:

(1) New wood.--Color -- purplish green. Bark -- smooth.

(2) Old wood.--Color -- dark green. Bark -- smooth.

E. Thorns:

(1) Thorns.--Quantity (main stalk) -- ordinary. On laterals from stalk-- few. Form -- flat base. Length -- medium. Color -- purplish.

F. Winter hardiness: Needs protection in severe climates.

I claim:
 1. A new and distinct variety of rose plant of the Grandiflorarose class, substantially as shown and described, characterizedparticularly by attractive bright orange flowers.
